ECONOMIC FUNDAMENTALS AND URBAN-SUBURBAN DISPARITIES
构建空间显性模型，研究收入上升或通勤成本下降等经济基本面变化如何导致城市与郊区社区的不同演变，发现城市蔓延、收入隔离和辖区差异往往共存。
ABSTRACT This paper develops a spatially explicit model to examine how urban and suburban communities evolve differently with changes in local economic fundamentals such as rising income or falling commuting costs in the metropolitan area. The model highlights the importance of environmental amenities and the economy of scale in the provision of public services as determinants of urban spatial structure. Results suggest that urban sprawl, income segregation, and jurisdictional disparities are driven by the same economic conditions and thus tend to co-exist. Rising incomes or falling commuting costs for high-income households in a metropolitan area tend to increase land prices and public services in every community, while rising incomes or falling commuting costs for low-income households can have the opposite effects.
